The following weapons are seen in the anime series Elfen Lied:
File:Vector1.jpg The primary "creatures" in the series are a murderous female race called Diclonius, and they can only be harmed by high caliber bullets such as .50 caliber bullets.
File:S.A.T.jpg MP5 Used by the Japanese S.A.T officers as standard issue submachine guns.
File:Bondo1.jpg The commando Bando has many failed attempts at killing the Diclonius until he leanrs that only high powered weapons can harm them. Here he holds his Desert Eagle.
Barrett M82 Used by a S.A.T sniper to shoot the Diclonius, Lucy, in the head. She was unable to deflect the massive .50 caliber slug, thus the resulting impact caused brain damage and the creation of a split personality ~ which in turn played for an important plot device in the series.
